MACHINE THE PRODUCTION 0F SUEDE COTTON CLOTH,

To all 107mm t may concern.'

Be it known thatrI, .IoI-IN'DANTA 'Iom- LiNsoN, a subject of the `King of Great Britain and Ireland, residing 'at'` Soho. Wvorks, Rochdale, in the county of Lancaster, England, have invented Ynenv and useful Improvements in or Connected with. Machines for the Production of Suede Cotton Cloth, of which the following is a specification. v n The invention is an improvement upon one for which I have obtained Letters Patent No. 1218131 for the production of cloth to imitate suede leather, in which rollers are used which comprises bars or lags of wood covered with carborundum and stretching rollers or expansion bars, in the combination making-up the complete roller. I fhid in practice, that while the carborundum lags are effective and produce a good result on the surface of the knitted fabric of fine Egyptian cotton such carborundum surfaces individually tend to produce somewhat lengthy fibres, like hairs, on the surface of the cloth. Such lengthy fibres are not necessarily got rid of by the next carborundum covered lag but their removal may require the successive action of several lags thus to some extent interfering with the sueding action by their very presence. As a result of this it may be necessary or desirable to pass the fabric more than once over the complete sueding roller or over more than one such rollers or` otherwise to control the speed or running of said roller. Such fibres or hairy lengths produced by one lag are not necessarily got rid of by a Succeeding carborundum covered lag although the end is ultimately accomplished. A too drastic action of the lags may pro-V duce a streaky result which is to be avoided.

According to my invention I propose to `apply to the sueding roller comprising a number of carborundum covered lags or bars and having rollers or bars, or other devices for maintaining the cloth in its curved form when traveling on the roller, one oi' more needle or wire covered surfaces 'to .assist the action of the carborundum and to produce a 'better surface on the cloth. A needle or wire covered surface can be ground to a uniform facewhereas a carborundum surface is necessarily uneven.

By means of the needle or wire covered surface, operating in cooperation with a carborundum surface, ysuch projecting fibers kSpecification of Letters Patent. Patented Blah 28 1922.1

arecaught as the cloth passes ,thereover, andV :i more uniform suede surface ispi'oduced.

In the accompanying drawings I' have indicated means for carrying the invention into effect. i

Fig. 1 is a cross section of the upper half of a sueding roller in whichI have indicated a rotary needle or wire covered surface, and also a rotary stretching roller Fig. 2 shows the lower portion of a sueding roller indicating a lag provided with a needle or wire surface, and also a stretching bar or lag and carborundum covered lags. i

Fig. 3 illustrates a part of the length of a sueding roller on a smaller scale than Figs. 1 and 2, with non-rotary stretching bars or vlags and similar non-rotary needle or wire covered bars combinedpwith y combinedwith carborundum covered lags.

tween two carborundum covered lags bon oi' aboutk the sueding ioller periphery so as to come into action after a carborundum covered lag l), the intention being that the needle or wire covered surfaces shall so act on or influence the projecting fibres or hairy vlengths which may be produced by a carborundum bar that thesame are removed by the action of they succeeding carborundum bar and the fabric will then be straightened out by a stretching roller or bar. At present I propose to employ card or other wire or needle surfaces arranged around a roller surface or in strips or lengths, or otherwise upon aV lag or bar, say in the space between any two carborundum lags or between such a lag and a' respect to the periphery of 'the complete sueding rollei. Also with a view to obtaining an' additional? lateral stretching oi' straightening effect upon the fabric the needle or Wire surface Vmay be disposed spirally from the centre outwards on theroller, or at the desired angles on the non-l rotary lag to have the same effect as far as possible upon the fabric as tliestret'ching rollers or bars.

I anticipate being able to get rid of such outstanding fibres or hairy lengths almost immediately` after their production wherebya betterV and more easily controlled result is obtained. Y y
